When You Need Furnace Replacement
A furnace doesn’t usually fail without warning. Here are the signs that tell us replacement is the smarter money move than another repair:
- Your furnace is 15 years old or older. Even well-maintained units lose efficiency and reliability past that age. In Pasadena’s older housing stock across neighborhoods like Bungalow Heaven, Madison Heights, and northeast Pasadena, we regularly replace furnaces from the 1990s and early 2000s that are running at 60-70% of their original efficiency.
- Repairs have totaled more than $800 in the last two years. That’s the point where the math tilts. A blower motor here, a control board there, and suddenly you’re halfway to a new system that carries a fresh warranty.
- Uneven heating between rooms. If some rooms are comfortable while others stay cold, your furnace may be too small, too worn, or your ductwork is fighting an aging system. We see this often in Pasadena’s hillside homes where duct runs are long and older furnaces can’t keep up.
- Carbon monoxide alarms have gone off. Don’t wait on this one. A cracked heat exchanger can leak carbon monoxide. If your detector has triggered, shut the system off, ventilate the house, and call a professional immediately. Replacement is almost always the right answer here.
- Your energy bills keep climbing while comfort drops. An aging furnace works harder to produce the same heat. In Pasadena’s mild winters, you shouldn’t see gas bills spike during December and January for the same thermostat setting.
- Frequent cycling or the system won’t stay lit. Short-cycling, pilot issues, or a blower that runs constantly are late-stage symptoms. They usually mean the core components are spent.
Our Furnace Replacement Process
Here’s exactly how a furnace replacement works when you call Dalton Heating & Air Pasadena:
- Call and talk to a real person. No voicemail queue. You’ll reach our team at (626) 657-5344, day or night. We’ll ask about your current furnace, the size of your home, and what symptoms you’re seeing.
- We send a background-checked, uniformed technician. You’ll know who’s coming before they arrive. We service all nine major residential HVAC brands including Carrier, Trane, Lennox, and Goodman, so whatever’s in your home now, we can size a proper replacement.
- We run a full load calculation and inspect your ductwork. This is the step that separates a guess from an engineered fit. We measure square footage, ceiling height, window exposure, insulation level, and duct condition. In Pasadena, older homes with minimal insulation and single-pane windows need different sizing than newer construction.
- You get a written price before any work starts. The number covers the furnace, installation, permits, haul-away of the old unit, and any duct modifications. That price does not change unless the scope changes, and we’d put that in writing too.
- Installation day. We remove the old furnace, set the new one, connect gas lines and venting, run the electrical, and start the system. We protect floors with drop cloths and leave the site clean when we’re done.
- Final walkthrough and written guarantee. We show you how to operate the thermostat, explain the filter schedule, and hand you a written guarantee covering the installation for a full year. If anything isn’t done right, we come back and make it right at no charge.
Furnace Replacement Pricing in Pasadena
Here’s what you can expect to pay for a furnace replacement in Pasadena, based on the jobs we do most often:
| Furnace Type | Typical Installed Price Range |
|---|---|
| Single-stage, 80% AFUE, 60,000-80,000 BTU | $4,200 – $5,500 |

Call (626) 657-5344 for an exact number for your home.
Is it cheaper to repair or replace my furnace?
If your furnace is under 12 years old and the repair is under $450, repair wins. If it’s 15 years or older and you’ve spent more than $800 on repairs in the last two years, replacement is almost always the better long-term financial decision. Our technicians will tell you straight, even when the answer is a smaller repair bill. Call (626) 657-5344 and we’ll assess it honestly.
How long does a furnace replacement take?
A standard furnace replacement takes one full day, about 6 to 8 hours. If ductwork modifications are needed, it may run into a second day. We’ll tell you the timeline in writing when we give you the quote, and we show up on the day we say we will.
Can you replace my furnace today?
In most cases, yes. We keep common furnace sizes stocked, and our team can often perform a same-day or next-day replacement in Pasadena when the unit is in stock.
